Length for station - River ID field in river feature OID 2 is not populated

[XavierAllègre1]

Hello,

I am working with ArcMap 10.2 and Hec GEO-RAS and I have the following error messages when I click on RAS Geometry -> Stream centerline Attribute and then Lengths/Stations :

"River ID field in river feature OID 2 is not populated."

When I try to click RAS Geometry -> Stream centerline Attribute -> All I have the following warning :

"Error occurred in Stream Length Tool"

I have a pretty long river (subdivided in several reaches with the same name, for convenience of the use of the "saving edit" while I was drawing the river) so it would be nice if anyone could help me solving this issue.

Many thanks.

Maybe because there are sub-branches to branch of main river.After i deleted these branches with sub-branch,the error disappears. Hope this can help you .
